Answer:
D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 4(x - 10) ← is in point- slope form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
The perpendicular line passes through (- 3, 7), hence
y - 7 = - (x - (- 3)), that is
y - 7 = - (x + 3) → D
Answer:
The least common denominator, also called lowest common denominator (LCD), of 10 and 15 is 30.
Step-by-step explanation:
Answer:
A=24m^2
Step-by-step explanation:
to find the area of this figure you can approach it multiple ways, the simplest way is to split it into two rectangles
respectively one 6m by 3m and another 3m by 2m
find the areas of each rectangle and add them both to get the total area of the figure
(6m*3m)+(3m*2m)=(18+6)m^2=24m^2
Answer:
x = 8√5
Step-by-step explanation:
for right triangle
c^2 = a^2 + b^2
with c is the hypotenuse; a & b are the other sides
(4 + 16)^2 = (4√5)^2 + x^2
400 = 80 + x^2
x^2 = 320
x^2 = 64(5)
√x^2 = √64(√5)
x = 8√5
Divide 5 by 2 = 2.5 per 1/5 an hour
there are 10 of 1/5 an hour in 2 hours
so 10 X 2.5 = 25 miles in 2 hours
